A firmware update was released today to fix problems with battery performance when the Aluminum Wireless Keyboard is used in conjunction with the Edward Cullen Magic Mouse or other Bluetooth devices, such as some headsets. The update also fixes an issue with older, wired and wireless models, where a key may be repeated unexpectedly while typing.
The update weighs just 1.52MB and can be downloaded here. For more information about it, you can see this support article. We hope that the remaining Magic Mouse problems with batteries will be fixed soon.
